Steam boiler When should an emergency shutdown when the 12 bars fired steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.
Free supervisory inspection principles and characteristics of small 12 bars fired steam boiler as the country increasingly stringent security checks on special equipment, many users are in for acceptance steam boiler to worry about, then there a boiler inspection and acceptance does not require it? The answer is yes, this is the free acceptance boiler steam boiler, supervisory inspector now free to receive more and more small steam boiler users of all ages, so check the small steam boiler-free monitoring What are the principles and characteristics of it? Then we explain for everyone. First small steam boiler uses a very broad, such as industry, food processing, school canteens, washing rooms, hospital disinfection, hotels, district heating, etc., there are coal, oil and gas heating, where coal-fired steam boilers currently in my company alone this one domestic production, steam boilers do not build a separate boiler room, small size, light weight, easy to move, can be placed in the basement, roof, etc., the Boilermakers do not need to operate licensed fireman, replacing every year dealing with government departments, small steam boiler-free acceptance than conventional boiler safety, this boiler will not explode, it is composed of a coil, burning very fast start, whether it is coal, oil or gas to ensure 3 minutes to a steam, does not require inspection and monitoring of the subject. Overpressure, over-temperature combustion, water and other multiple protection, ultra-safe, non-explosive, can greatly reduce the burden on the user.
Talk about the overall structure of the furnace boiler boiler boiler and auxiliary equipment, including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Today, we are concerned that the furnace boiler. Also known as boiler furnace combustion chamber, fuel combustion for space. It solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as the fire-bed furnace. Solid fuel liquid, gas or pulverized, is injected into the furnace fire chamber may be referred to as a combustion chamber of the burner, also known as the furnace fire chamber. The coal particles and air hold it was boiling point of combustion, the furnace and adapted called inferior fuel combustion fluidized bed furnace, known as a fluidized bed furnace. An air flow so that the coal particles rotated at high speed, and strong burning furnace called cylindrical cyclone furnace. Boiler furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. In addition, the furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion.Free Chat
